Mugen 3200mAh battery for TP2 works in EVO

In case you need an extended battery now, I can report success with a Mugen 3200mAh unit that was intended for a Sprint Touch Pro 2. It cost $70 or 80 when I bought it around Christmas time from an eBay vendor (couldn't find it anywhere else online). Turns out the person I got it for had a Touch Pro 1 and this battery was not compatible so it's been sitting around the house ever since. I just popped it into my EVO 4G and it works perfectly as far as I can tell. Boots up normally and is charging as expected. Of course the back plate does not fit over the fat battery so I left that off and replaced the jelly case which stretches over the whole thing well enough.

Hero batteries work also.. a lot of HTC phone's use the same batteries. I have like 4 batteries for my evo lol
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280492889203&ssPageName=STRK:MEWAX:IT
I bought these a while back.. worked great in my hero and work just as good in my evo. Plus now I have a standalone wall-charger. Took about a week or so to get here since its coming from Hong Kong.. But it was well worth the ~$10 for 2 batteries and a charger..

ok, i stole its soul for you.

well im glad i order mine from seidio since it comes with the back case but this is good info so i can pass my oem battery to my wife for hero hero with weak battery life

Lol. Nice evo . It's the humpback of xda.
Sent from my Evo 4G

that is disgusting! but more power to you hahaha...lets hope seidio lets you buy just the ext battery cover

oh sweet mother of god i would feel all grossed out if i tried to handle my phone and it was all squishy at the parts that aren't touching the battery or the frame...
How's the battery life with the 3200? After doing some battery life tweaks and mods mine seems to almost be sufficent with the stocker, but it can always use some improvement.

If you don't mind sacrificing the case, I would try cutting a rectangle in it that would leave the protruding part of the battery exposed and let the case hug the phone the way its supposed to. If you cut it just right, the batt should stay in place since it looks like it has a bit of an edge for the case to grip on to.

I'M starting think I should just cancel my order for the 3500 battery and get me 2 1500. What do you guys think?

I'm using the battery from my tp2 as a spare, and carry it in the smaller pocket in my jeans,i don't even feel it there sometimes. With battery tweaks and charging it in my car (usually around 30 min at a time), I only have to occasionally change to the 2nd battery. If you are sensitive to bulk, then go for 2 batteries to split the load, otherwise a bigger battery is more convenient.

Given some of the results from BatteryBoss, I'd say that the battery isn't going to perform at a full 3500mAh. It will still be more than an OEM battery, sure, but I couldn't justify doubling the size of the phone to put it in. You might be better off getting another OEM battery, HTC seems to give about 99% of what they say.

if that site batteryboss is accurate then Mugen's batteries are crap. twice the size for 50% more juice. however, some anecdotal evidence to the contrary: after buying the wrong one, i bought another Mugen extended battery that does work for the TP1 and the recipient is very happy with it. reports that the 3200mAh it lasts about twice as long as the OEM battery.
probably smart to just get another HTC 1500mAh. after the latest update battery drain is much less of an issue anyway.

So can I just go in to a sprint store and ask for a hero battery For free?

The batteries + charger that was listed earlier in this thread work GREAT I've been using them for a few days now great freaking deal ($10 shippped)

Anyone know if the Tilt battery here will fit the Evo with a modified case / back plate? http://www.amazon.com/HTC-Extended-Li-Ion-Battery-RHOD170/dp/B002Y24MJ2
I know Seidio makes a modified back plate that looks like it would fit this and according to battery boss this is the gold standard of extended batteries.

Also confirmed, the Mugen 4500mAh battery for Sprint Touch Pro 2 works in the Evo as expected. It's very... thick. About as thick as the Evo with a jelly sleeve on. Put together it's like the Evo has it's own little podium to stand on.
Assuming batteryboss tests are accurate then true capacity is closer to 75% or ~3375mAh. Main purpose for me is a power supply that can run GPS tracking apps like Cardio Trainer all day uninterrupted. Thickness not an issue since the whole package is tucked away in a Camelback.
Got it on eBay, I don't know where else to find them. Mugen is OOS and ridiculously expensive anyway. An alternative would be an external battery pack that supplies power through a USB port, then cable it to Evo.

under $4.00, 3500 extended battery for evo

USA shopper too, no back but if you are like me and already have one why spend more to get another back

For this being only your second post, it sure does look a lot like spam advertisement.

Considering the hellfire conflagration a bad Lipo Battery can cause, I would be nervous about buying cheap knock-offs. If Seido charges $70 for these and someone else charges $4, you gotta wonder what you are getting. I doubt Seido has a $66 markup on their batteries.

it's not something just a deal on a cheap. battery if you want a spare or if like me your charge port is broken and use a few batteries and wall chargers, if you want to spend $9 for the same battery with a back cover go ahead, not Spam just a good deal, show me a better deal for a cheap extended battery. like I said I don't charge the batteries using my phone so these work great, good to charge and leave in the car or plus its always have a normal sized battery in my wallet

TEP covers broken usb ports too. I got a brand new Evo when I took mine in for repair.

I bought my evo used but tried to do the Touchstone mod and messed up sodering or something and now the charging port does not work and the g sensor doesn't work, but I do not miss cord charging I got like 5 batteries and 3 external chargers, that cost me like $30 for all that off cheap ebay sellers, so I always have like 3 batteries always charged and ready to go, don't even miss cord chargers any more

Actually, I wouldn't be surprised if Seidio had that large of markup considering they sell cases with a holster for $50. Which of course is just two pieces of molded plastic with a bit of psuedofelt and rubber finish. And which in my case, started to fall apart within 6 months after purchase. Frankly I don't think Seidio is the slightest bit better than the cheap eBay sellers, they just make a lot more money based on the perception that the charge more so they should be better.

Exactly alot of companies leverage their name so they can sell the same thing as other suppliers at a higher markup. It's good to know that alot of "manufacturers" don't actually make their own product, they actually contract out alot of their products.

Eh... $4, i'll bite.. We'll see how it works out.
Total for this and an external charger was like $7, so not too much money lost.

I purchased a couple things from them already off of ebay. Shipping was a couple days longer than I expected but they are reputable. My battery I got from them also works great...

Finally got around to testing it...
Charged it with the phone off, unplugged and turned it on.
Charged it until indicated green then unplugged then powered down.
Repeated this process four times until icon indicated 100% power.
So far I'm down to 11% and have been going 42 hours and 50 minutes with my normal use (texting, couple calls, light internet use, light gaming).
All in all for $4, great purchase. I was even more so surprised when the eBay seller contacted me and told me it would not fit with the stock battery door (I already knew that personally). They informed me that I would be getting a battery cover I believe, or a full refund.
I didn't mind either, so I just said whatever works.
EDIT:: Checked my inbox today, and they are sending a back cover it looks like.
"Now the battery cover in stock ,and we have send it to you for first time ,this is the tracking#:removed
Would you pls check it later on www.usps.com"
Fun grammar, so we shall see what this holds in store for me.

Are they still for sale?
I made an offer for the same price as the recently accepted offers and got rejected

When I went back to purchase another, they were $104 and some change.
My thoughts are they realized they did not fit the stock EVO and they needed to revamp their posting and or include a battery door.

Do a search on ebay, I found some by a couple different posters.
I can't post links yet but they are about $10

I charge mine with an exteral wall charger just for the battery, and between my two 3500 batteries in can go two days with each battery, but I usually just swap them every morning

I received my 3500mAh chinese battery yesterday and used it until it died. I charged it over night and unplugged it at 6am this morning. When I first pulled it off the charger it immediately dropped 6%, from 100 to 94. At first I was like WTF but I know the USB/AC Charger is notorious for this so I paid it no mind. It's nearly 3pm here and my battery now has 8% life left. Almost 9 hours battery life... something my 1800mAh chinese battery was already able to do. I know I can't expect much from a $8 battery, but I thought it would put out more juice than my stock one at least.... am i missing something?

Thanks. I didn't think about using the external charger, so hopefully tomorrow's performance will be better than todays. I'm curious though, if the 3500 battery wasn't fully charged, why did it show as 100% before I unplugged it?

So I let my 3500 battery charge for over 12 hours on an external charger. I've had it in my phone for 10minutes now and its already dropped 10%. 0_o

Because no one can find the friggin 1650s. Even the post dedicated to them doesn't have more than a dead ebay link for them.

why get the 1650 when u can get 2800 on amaZON for under 20.00 us?

Well anything higher than 1600mah will cause the phone to get really fat.
I posted link above.

fat battery
I got one of those fat batteries from amazon and it doesn't seem to last that much longer than a standard battery. It also makes the phone look pregnant.

I am using a 3.7VDC 3500mAh Li-ion Battery for my vibrant and it lasts me for 2 days and a half without charge, Of course the battery is a little bulkier then the normal 1500mAh, & it comes with a back Case, its worth the cost and its for only $16 Bucks on ebay. Its worth the money Sweet

Well actually the battery was working fine when I received it. What you want to do is once you have the battey, deplete it till it fully drains out of power. Then recharge it with the charger they supplied you, don't charge it throu the phone. Once you see its fully charged. Chharge it for at least 1 hour more and u will get the full capacity of the battery. If your vibrant has a good kernel u will be set for 2 days straight. Hope that helps. Am using overstocked kernel

...he said dont charge it through the phone, which is the only way you can use the vibrant charger so that rules that one out, so by process of elimination and a lil bit of thinking the only option left is his came with a charger for the battery, probably a small dock type deal.
Just gotta think a little not too much to ask

i apologize for the late reply, I should of been more specific with the charger i was talking about. It is a USB/AC Wall charger for the Samsung Galaxy S i9000, Sprint Epic 4G, AT&T Captivate i897,T-Mobile Vibrant T959. You can view it on ebay, Amazon etc.

Affordable Extended Battery

I got one from an Amazon seller for $12. I think it's 3,700 mah and I easily get a day out of it. However, it's stupid to use something that large and that adds weight and bulk to such a thin and light device. Especially when it's just as inexpensive and easy to simply buy 2 or 3 stock-sized batteries and a wall charger on eBay. I carry 1 or 2 spare batteries in my back pocket and don't even notice they're there. Why wouldn't you do this?

im currently testing this one.
on my 2nd cycle right now with 26% left im at:
21hs up time, 3hrs screen time about 1hr Pandora. been on 4G/3G the whole time with all my radios on but GPS.
it seems like im getting about 30% more life out of this batt vs the OEM. which seems to be getting me over a full day of use with out needing a charge.

MUGEN is a great brand, i know because i own their battery for my G2 and S2, you get what you paid for man. on test i found that the MUGEN outlast the SEIDO by 30-40 min screen on time under hard benching...now this data is of course base on S2 battery.
right now i am testing Hyperion, look for my post, i will give more update soon as i am on my 3rd full charge right now, will bench by the end of the week. I am in talking with MUGEN and Anker to give me a free sample to do a review on their battery,

id agree that "namebrand" batteries tend to yield better results.
in fact i would have personally preferred a Samsung Extended battery. but i cant see spending $100 one a 4000mAh battery from Mugen when a replacement 63Wh batt from Samsung for my M11x is $125.

Just throwing out counterpoints: It can be a hassle to have to shut down, take the phone out of a case (if you have one), swap batteries and put it back together, etc. With an extended, you don't miss a beat. Also, since the phone is thin and light, having a big, heavy battery isn't so bad -- makes it feel about the same as a lot of older phones.
That said, I'm using a stock battery, but have been considering a nice extended battery eventually.

I just don't see how any one can justify carrying extra batteries on a +600$ phone?
I mean the battery life is great already, not shabby by any means. I got 1d 11h with 3 hour screen on time on my Verizon phone this weekend on stock battery. But no call or hotspot like I do during my work day. But a ~2500mAh would probably last me the whole day even on a work day. I'd pay $45 for that with nice cover. (slightly thicker won't be such a bad thing on this phone)
I have few more days before I can return this phone to verizon for full purchase price of 600 bucks. But it's making me think twice about returning it because it's still 2x better than my rooted galaxy nexus.

Carrying extra batteries, at least for me, is zero hassle. They slip into my back left pants pocket and I never even notice they're there. Granted, I can see swapping batteries being somewhat of a hassle for some people but, even if you had an extra step in removing a protective case, how long could it really take? 1 or MAYBE 2 minutes? This phone shuts down quickly and boots up just as fast.

My Review after 6 months of the 3800mah extended battery with cover

In the beginning it gave me around 2-2.5 days worth of battery per charge which was fantastic. The extended battery weighed about 3x the stock battery for outputting almost 2x. I liked the fact that it lifted the phone up so it wouldn't damage the camera lense (since the lense does stick out past the back cover). It was the same plastic as the rest of the phone so it made the phone look stock.
But after about 5 months, the battery capacity greatly decreased to the point where I was getting about 7 hours until I received the 20% battery warning. This battery was preforming worst than the stock battery.
So in the end I went back to the stock battery. What was everyone else's experience with these extended batteries?

Thanks. I was just shopping for an extended battery this morning. My stock battery is still doing okay after 14 months, but I wanted something to counter the effect ICS has had. I saw Seido's on sale at Newegg and was about to pull the trigger, I'll hold off until I hear more.

you might as well give it a try. I bought mine for around 10usd

Would you mind indicating exactly which 3800mAh battery you are reviewing?
Cell phone batteries and memory cards both suffer from a large amount of poor-product masquerading as quality. Reviews of this type of product are not actually helpful unless they identify the specific product, brand, and even seller.
I wouldn't be surprised in the slightest if I purchased an extended battery for $10 and it started to go bad after 5-6 months. As comparison, my stock battery went bad after about 13 months. While paying more doesn't guarantee that you'll get something great, it is generally true in my experience that you get what you pay for.

I hope you're right. I just got mine today and I'm using it right now after it hit 100% charge. I hope this didn't turn out to be a waste of money. How long did the Gorilla batteries last for you on average? (not phone battery life but the actual battery itself life)?

Yeah, after three trexcells, two that need to be thrown out because of bulging, I just got a qcell 4100. I know the number means nothing. It said to do 6 full charge and discharge cycles in the beginning, and let the first one charge for nine hours. I'm on my second charge so far. Don't know if it's true but I read somewhere to charge with the phone off. The first charge ran reaaaly long before dying. Don't know if it was bad batteries or bad external chargers, but both my Samsung externals would only charge the trexcells to 95%, even if it was a 12+ hour charge.

Here I am about 4-5 months in on my 3800 batteries. 1 trexcell and 2 generic. Far as comparing to stock? Stock batteries make me sick now. They drain so much faster. The big ones amaze me how long they last. I do rotate the stockers in so they dont sit and go bad. So ill have a few days of extended then stock then extended ect. The performace of extended is so good I now see the big lump as sexy! I did find a great use for my stockers. (have 4) I was in my best friends wedding the other day and with no case and slim battery the phone slid in tux pocket easy lol. +1 but half way through reception I had to drunken walk way out to car and get spare -1. Right now as I set im about to hit 2 days on Trexcell on the newest Jellyverse sitting at 37% +20.
